Washington, March 23, 2017: In a step towards verifying the efficacy of laser communications for speedier data rates for connections between spacecraft and the Earth, NASA said it is developing a trailblazing, long-term technology demonstration mission.

The Laser Communications Relay Demonstration (LCRD) mission, scheduled for launch in 2019, will help NASA understand the best ways to operate laser communications systems, the US space agency said in a statement on Wednesday.

They could enable much higher data rates for connections between spacecraft and the Earth, such as scientific data downlink and astronaut communications.

“LCRD is the next step in implementing NASA’s vision of using optical communications for both near-Earth and deep space missions,” said Steve Jurczyk, Associate Administrator of NASA’s Space Technology Mission Directorate, which leads the LCRD project.

“This technology has the potential to revolutionize space communications, and we are excited to partner with the Human Exploration and Operations Mission Directorate’s Space Communications and Navigation program office, MIT Lincoln Labs and the U.S. Air Force on this effort,” Jurczyk said.

Laser communications, also known as optical communications, encodes data onto a beam of light, which is then transmitted between spacecraft and eventually to Earth terminals.

This technology offers data rates that are 10 to 100 times better than current radio-frequency (RF) communications systems.

Just as important, laser communication systems can be much smaller than radio systems, allowing the spacecraft communication systems to have lower size, weight and power requirements.

Such capability will become critically important as humans embark on long journeys to the moon, Mars and beyond.

“LCRD is designed to operate for many years and will allow NASA to learn how to optimally use this disruptive new technology,” Don Cornwell of the Space Communications and Navigation programme office at NASA Headquarters said.

“We are also designing a laser terminal for the International Space Station that will use LCRD to relay data from the station to the ground at gigabit-per-second data rates,” Cornwell said.

“We plan to fly this new terminal in 2021, and once tested, we hope that many other Earth-orbiting NASA missions will also fly copies of it to relay their data through LCRD to the ground,” Cornwell added.

The LCRD team is led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Partners include NASA’s Jet Propulsion Laboratory in Pasadena, California, and Massachusetts Institute of Technology’s Lincoln Laboratory. (IANS)

NASA is inviting applications from start-ups to take part in a three-month pilot programme to develop new technologies for space.

Applications will be accepted till April 7 and a total of 10 companies will be selected for the programme, the US space agency said.

The accelerator programme will focus on technologies that can be applied to space — including geospatial analytics, digital design coupled to advanced manufacturing, autonomous systems, applied Artificial Intelligence (AI) and Machine Learning (ML).

“We want to assist these companies in developing their own technologies and becoming commercial successes. NASA will also benefit by collaborating with these companies,” said Tom Cwik, Manager of the Space Technology Office at Jet Propulsion Laboratory (JPL) in Pasadena, California.

Based in Los Angeles, the accelerator programme begins on July 15. After developing their concepts and business plans over a three-month period, the teams will then pitch their results to the NASA community, co-sponsors and private investors at a demo day in October, NASA said.

“Industry is developing new technologies rapidly, using new tools and methods in software development and other areas,” said Cwik.

“It’s incumbent upon us to learn from developments in industry and contribute our vast expertise in technology as we prepare to use them in our future missions,” Cwik added. (IANS)
